Expand description

Indexer

Accepts the RPC operational functionality hopr_chain_rpc::HoprIndexerRpcOperations and provides the indexing operation resulting in and output of hopr_chain_types::chain_events::SignificantChainEvent streamed outside the indexer by the unbounded channel.

The roles of the indexer:

  1. prime the RPC endpoint
  2. request an RPC stream of changes to process
  3. process block and log stream
  4. ensure finalization by postponing processing until the head is far enough
  5. store relevant data into the DB
  6. pass the processing on to the business logic
